She has been carrying it for six years, twice a week, and I have never once dropped it for her.
Right now it rides against her hip: eleven pounds of shirts, one towel still damp at the center, a sock that will not survive the trip. She leans back to counter it. This is my favorite thing the body learns without being taught, this quiet negotiation, the spine tilting to let me pull the load through her instead of off her. She does not know she is doing math with me. She thinks she is just walking.
She has stopped on the stairs. She sets the basket down on the step above her, both hands resting on the plastic rim, and she is not folding anything, not lifting anything, just standing. I check her. The basket weighs eleven pounds. She weighs one hundred and thirty. I add them and I hold them, easily, the way I hold the stairs and the house and the town and the pale rock hanging outside the window that I also never release.
But something is on her that I cannot find. She says it into the empty stairwell, quietly, that she is so tired, that it is all so heavy lately. I have measured her a thousand times a second since she was born and I promise you: there is nothing extra there.
No mass. No pull. And yet she bows under it, deeper than the basket ever bent her, her shoulders coming down toward me like she is asking to be set down herself.
I cannot lift that one off her. It is the only thing I have ever been unable to carry.
So I do what I can. I hold the stair beneath her feet. I hold her, and the basket, and the damp towel, and the doomed sock, for as long as this takes.
I have not let go of anyone yet.
